DSS-caused abnormal clinical symptoms were scored using the disease activity index (DAI). Male C57BL/6 N mice (8-weeks-old) were administered with (a) 1%, (b) 2%, or (c) 3% of DSS in drinking water for 7 days. DAI scores indicate the severity of abnormal signs including body weight loss, diarrhea, and rectal bleeding. Differences in the DAI scores between the sub-strains were not found
